Title: Production of carbonyl compound
Inventor: OGURA FUMIO
IPC: C07C49/12
Filed: 1986-09-24
Abstract: PURPOSE:To obtain the titled compound suitable for many uses by oxidizing a compound containing an active hydroxyl group, and by selectively oxidizing an active hydroxyl group by the use of an aryltellurinic acid anhydride without changing other substituent groups. CONSTITUTION:A compound containing an active hydroxyl group is oxidized in the presence of a compound shown by the formula [Ar is aryl which may contain one or more substituent groups (e.g. 1-8C alkyl, alkoxyl, substituted or unsubstituted amino, substituted or unsubstituted phenoxy, benzyl or halogen)] to give a carbonyl compound such as aldehyde, ketone, etc., corresponding to the raw material. Since oxidizing action by the compound shown by the formula is moderate and has selectivity, this method is applicable to cases wherein the active hydroxyl group contains various substituent groups and the active hydroxyl group is selectively oxidized without changing the substituent groups so that many useful carbonyl compounds can be produced.

Abstract: PURPOSE:To enhance the stability in capacity control by furnishing a double-acting hydraulic cylinder for oil amount control, No.1 valve device for changing- over of pipeline, and No.2 valve device for the same purpose. CONSTITUTION:To increase the capacity of a screw compressor body 3, i.e., to move a slide valve 2 to the right, the solenoid SL1 of a spring offset type solenoid valve 13 (No.1 valve device 5) is turned on, and pressure oil is sent to a pipeline 9 by an oil pressure pump 7.

When this motion is ended, the solenoid SL2 is turned off, and pressure oil is sent to the space B of cylinder 4 by the pump 4, while the pressure oil in the space A is sent to the space C, and the piston 11 is moved right for one pitch. These motions shall be repeated.

Filed: 1983-11-30
Abstract: PURPOSE:To prevent a thrust bearing from bearing of radial load by making the holding system of thrust bearing for mainly bearing the thrust load occurring in rotor flexible in radial direction. CONSTITUTION:The outer shaft 70 of thrust bearing 7 is held by a ring 10 and a holding system 11 comprised of a stopper 12 having a circular flange section 12a and a stud 13 for fixing said stopper 12 movably against main casing 3m only in radial direction. The stud 13 is constituted with a threaded section 13a to be screwed into the casing 3m, small diameter section 13b, threaded section 13c to be screwed with a nut and a nut 13d where the small diameter section 13b will flex upon application of force at the free end. Consequently, upon occurrence of thrust in rotor 2 in the arrow direction A, the thrust bearing 7 will be displaced radially to scarcely bear the radial load.

Title: Waveform arranging circuit
Inventor: MAEDA KEIJI
IPC: H04L25/08
Filed: 1988-09-07
Abstract: PURPOSE:To prevent a transmission error from occurring due to the accumulation of waveform distortion by discriminating whether or not a signal is a digital signal emitted normally from the duration of a reception signal by using a counter circuit, and generating a synchronous pulse setting the fall time of the reception signal immediately after as reference. CONSTITUTION:A clock signal generation circuit 7 generates a clock pulse (a) with time width of one even-th of bit time width T that is the time width of one bit of the digital signal. When the reception signal is sampled by the clock pulse, the count of the clock pulse is started at a time when the reception signal rises to an H level and the H level continues until the number of count arrives at a prescribed value decided by the bit time width and the transmission delay time of a transmission path and a pulse with the width sufficiently shorter than the bit time width can be generated, and next, when the reception signal falls to an L level, the synchronous pulse can be generated. In such a way, it is possible to eliminate the waveform distortion based on transmission by arranging the signal to the same waveform as that at the transmission terminal of the reception signal without consuming the preamble part of the signal.

Title: Casing of rotary electronic component with flat cable and manufacture thereof
Inventor: YAGI NOBUYUKI
IPC: H01C10/20
Filed: 1987-09-07
Abstract: PURPOSE:To eliminate the need for the assembly of a casing and a substrate and the connection work of a flat cable, and to miniaturize and thin an electronic part by monolithic-molding the substrate and the flat cable by a high-temperature resin film and inserting the substrate section into the casing. CONSTITUTION:With a thermoplastic heat-resistant film 1, a flat cable section 2 and a substrate section 3 are unified, resistor patterns 3-1 and current collecting patterns 3-2 are printed onto the substrate section, and lead patterns 2-1 continuing to these patterns are printed onto the flat cable section. Resist layers are formed onto the lead patterns, and insulated electrically. Consequently, a large number of the heat- resistant films to which the current collecting patterns and the resistor patterns are shaped can be formed onto the same film by support sections 1-1, 1-2. The end sections of metallic terminal pieces 5 are placed onto the end sections of the lead patterns. A film for fixing terminals having the same quality as the heat-resistant film 1 is placed onto the end sections of the metallic terminal pieces 5, and ultrasonic-heated and melted. The substrate section in the heat-resistant film constituted is inserted into a casing 4 composed of a synthetic resin, and the support sections are removed, thus completing the casing of a rotary electronic part.

Title: Cleaning device
Inventor: INO SHOJI
IPC: B08B9/093
Filed: 1992-07-30
Abstract: PURPOSE:To provide a cleaning device which can seal airtightly a gap between the outer peripheral surface of a hose and the opening part of a tank with a liquid (water) easily removable from the tank side after cleaning work. CONSTITUTION:A high pressure water is continuously discharged into a gap between the inner peripheral surface of a seal part 10 and the outer peripheral surface of a hose 21, that is, an annular space 16 from water supply pipings 35a, 35b through the water supply path 15b of a seal block 15. The cross-section of the water supply path 15b is smaller than the vertical cross-section (an area facing the outer peripheral surface of the hose 21) of the annular space 16. However, since water is non-compressive, a high pressure is maintained at the same level as the interior of the water supply path 15b, if the water is introduced into the annular space 16. Thus, a large amount of higher pressure water than the internal pressure of the tank is always present in the annular space 16 and thereby the gap is completely sealed airtightly.
